1. What is the Mortgage Interest Rate Calculator?

The Mortgage Interest Rate Calculator estimates the interest rate for UK mortgages based on your monthly payment (EMI), principal amount, and loan tenure. It helps you understand the effective interest rate you're paying on your mortgage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( EMI \) — Monthly payment amount (GBP)
• \( P \) — Principal loan amount (GBP)
• \( N \) — Number of monthly payments
• \( R \) — Monthly interest rate (decimal)

Explanation: The calculator uses an iterative numerical method to solve for the interest rate that satisfies the mortgage payment equation.

3. Importance of Interest Rate Calculation

Details: Understanding your effective mortgage interest rate is crucial for comparing loan offers, financial planning, and making informed decisions about refinancing or additional payments.

4. Using the Calculator

Tips: Enter your monthly mortgage payment in GBP, the original principal amount in GBP, and the total number of monthly payments. All values must be positive numbers.
